Under what circumstances would you rebuild the content index from scratch, and what is a major drawback?

• A. When the index becomes out of sync or outdated; the drawback is that it can take a significant amount of time and users will be unable to search during the rebuild.
• B. For minor updates; drawback: immediate search availability
• C. Only after license renewal; drawback: data loss
• D. To reduce storage; drawback: increased index size

Answer: (B)

Rebuilding the content index from scratch is used when the index has fallen out of sync with the actual content or has become significantly outdated, such as after large content changes, migrations, or detected indexing corruption. Rebuilding ensures search results reflect the current content accurately by re-creating the entire index from the ground up. The major drawback is that this process is time-consuming and typically makes searching unavailable while the rebuild is in progress. Users can’t rely on search during that window, which can impact productivity if the rebuild takes a long time. For minor updates, you wouldn’t normally do a full rebuild because it’s unnecessary and inefficient; incremental indexing updates are faster and keep the search experience available. License renewal isn’t related to indexing, and attempting to reduce storage isn’t the goal of a full rebuild, which can actually add load and doesn’t inherently shrink the index.
